My Speedometer gauge isnt working and Im hoping that I just turned it off somehow. This gauge is linked to the GPS, but is not reading the MPH. Only showing two hash marks when running down the river.Did I somehow turn the MPH off, as the other functions are working correctly? If so, How do I turn it back on?2010 PII w/ Yamaha HDPI (Yamaha Gauges)Thanks, Your Signature …
